We look at the division of 841621 by 75 
We want to divide 841621 by 75.

Moving on to step 1:
8 divided by 75 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 75

Moving on to step 2:
If we divide 84 by 75, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 84 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 75

Step 3:
75 goes into 91 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 75 from 91 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 75

Moving on to step 4:
If we divide 166 by 75, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 150 from 166 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 75

On to step 5:
75 goes into 162 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1122.0
Subtracting 150 from 162 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 75

Let's proceed to step 6:
75 goes into 121 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 11221.0
Deduct 75 from 121 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
If we divide 460 by 75, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 11221.6
If we take 450 away from 460, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
75 can be fit into 100 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 11221.61
Subtracting 75 from 100 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 11221.613
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11221.6133
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 11221.6133, and the remainder is 0.00025.
